Improve Gut Health to cut Salmonella Infection
نویسنده
چکیده
The Food Standards Agency has made it clear that it wants to see a reduction in the proportion of pigs found to be carrying Salmonella when they arrive at the abattoir. The most recent results published to date (2000) show that 23% of UK pigs arriving at abattoirs carry Salmonella in their gut with 5% of pig carcases and 8% of pork sausages testing positive for Salmonella. Cattle and sheep however showed only 0.2% and 0.1% positives respectively.

Influenza Virus Affects Intestinal Microbiota and Secondary Salmonella Infection in the Gut through Type I Interferons.
Human influenza viruses replicate almost exclusively in the respiratory tract, yet infected individuals may also develop gastrointestinal symptoms, such as vomiting and diarrhea. However, the molecular mechanisms remain incompletely defined. Using an influenza mouse model, we found that influenza pulmonary infection can significantly alter the intestinal microbiota profile through a mechanism d...
متن کاملPhages as Therapeutic Tools to Control Major Foodborne Pathogens: Campylobacter and Salmonella
Foodborne diseases are a growing public health problem worldwide with Campylobacter and Salmonella being the most common and widely distributed causative agents. These Gramnegative bacteria are common inhabitant of the gut of warm-blooded animals, especially livestock, being transmitted to humans primarily through the consumption of contaminated food of animal origin. Poultry meat and derivativ...
متن کاملSalmonella-Induced Mucosal Lectin RegIIIβ Kills Competing Gut Microbiota
Intestinal inflammation induces alterations of the gut microbiota and promotes overgrowth of the enteric pathogen Salmonella enterica by largely unknown mechanisms. Here, we identified a host factor involved in this process. Specifically, the C-type lectin RegIIIβ is strongly upregulated during mucosal infection and released into the gut lumen. In vitro, RegIIIβ kills diverse commensal gut bact...
متن کاملIntraspecies Competition for Niches in the Distal Gut Dictate Transmission during Persistent Salmonella Infection
In order to be transmitted, a pathogen must first successfully colonize and multiply within a host. Ecological principles can be applied to study host-pathogen interactions to predict transmission dynamics. Little is known about the population biology of Salmonella during persistent infection. To define Salmonella enterica serovar Typhimurium population structure in this context, 129SvJ mice we...
متن کاملDietary fructo-oligosaccharides and lactulose inhibit intestinal colonisation but stimulate translocation of salmonella in rats.
BACKGROUND AND AIMS It is frequently assumed that dietary non-digestible carbohydrates improve host resistance to intestinal infections by stimulating the protective gut microflora. However, compelling scientific evidence from in vivo infection studies is lacking. Therefore, we studied the effect of several non-digestible carbohydrates on the resistance of rats to Salmonella enteritidis infecti...
